. Application August 27, 1941, 'serial No. 408,446 2 Claims. (C1. 237-1)The principal object 4ofthe present invention isA to provide acomparatively simple, reliable vand inexpensive apparatus, devoid ofelectrical connections, and which shall be silent, ecient andself-controlledin operation and shall operate in conjunction with ahouse heating plant to 4automatically humidify the atmosphere or air ofthe house in consonance with the temperature thereof.

AOther objects of theA inventionwill appear 4from the followingdescription at-the end of which the invention will be claimed. i

y Generally stated, the invention comprises in connection with a heaterhaving a fire box which generates heat for-heating a house; the use of aboiler arranged in the re box and heated in consonance with the heatgenerated for house space heating; a tank and float valve coordinatedwith the feed pipe supplying what may be described as a trickle of waterat low pressure to the boiler and causing it to operate as a flashboiler in a noiseless manner; a pipe leading from the boiler anddischarging steam into the house space; regulating valves and acondenser tank connected with the last mentioned pipe for adjusting thesteam output from the boiler to the moisture requirements of the house,and drain connections.

The invention also comprises the improvements to be presently describedand finally claimed.

In the following description reference will be made to the accompanyingdrawing forming part hereof and in which the single figure is adiagrammatic view partly in section and partly in elevation illustratingfeatures of the invention.

Referring to the drawing, l indicates a small boiler which is operatedas a ash boiler as will be hereinafter explained. This boiler isinserted in any convenient way in the re box of the house heater notshown because too well understood to require description orillustration. The boiler I is automatically fed with water from a tank 2in which the float valve 3 maintains a substantially constant levelindicated at bv-b. The output of steam from the boiler I is introducedto the interior of the house, for example by means of a nozzle 4 placedunder a large suitably located radiator a. The steam introduced throughthe nozzle 4 is controlled by two valves 5 and 6 which adjust the steamoutput to the moisture requirements of the house and which when once setneed not be changed throughout the heating season, because the moistureoutput is proportional to the operation and drying effect of the heatingsystem. The water supply is maintained by a tap on the cold waterlsupply line 'I with a small tubing 8-to the oat valve 3 located in thetank 2 `which'may be of two gallon capacity. The tank 2 is so locatedthat it maintains through a small tubing line 9 a small supply of waterin the flash boiler, Iwhen cool,` for example about one and one-halfinches in the boiler. The boiler I is located in the fire box of thehouse heating furnace preferably on` the inside of adoor in place ofinsulation orat some other convenient place which will least interferewith the operation of the heater or main boiler. When heat -is generatedinthe fire box the water in the boiler I is soon evaporated and sincethe boiler Iis fed by a small line 9 at very low pressure the ensuingtrickle or modicum of water causes the boiler to act as a flash boilerin a noiseless manner. The steam thus generated passes out and up aninsulated copper tube I0 to the nozzle 4. Provision is made in the lineIU for safety, condensation and regulation. A T-fitting is installedclose to the boiler to drain oir condensate and provide fool proofsafety by running a tube I I from it to the bottom of the water supplytank 2, thus providing a seal and at the same time preventing theaccumulation of any appreciable pressure. Further up the line I0 anotherT is installed with the valve 6 close to its outlet. From the valve 6 atube I2 is run to the small fm radiator or some other form of condenserI3, the outlet of which is piped as at I4 back to the water tank 2. Thevalve and condenser provide means for taking care of surplus steam andform one of the control mediums. Immediately after passing through thisT another valve 5 is installed which provides the other medium ofcontrol and regulates the amount of steam passing out of the nozzle 4and up into the house space. .I5 is a drip pan arranged under theradiator a, and having a depending tube I6 through which the nozzle 4passes and this tube I6 is connected through a trap litil by a pipe I'lto discharge into the tank 2. The purpose of the drip pan is to catchany condensate which might drip from the radiator when the boiler I rststarts up with the radiator cold. There is a valve I 8 provided in thepipe 8. I9 is a drain valve at the bottom of the water tank 2. 20 is avalve in the line 9 and it is useful to facilitate removing the boiler Iif necessary and also for cutting down or adjusting the water supply tothe boiler to insure that it shall operate as a flash boiler. 2l is atap and drain valve useful in cleaning the boiler I.

Sediment is largely excluded from the boiler and supply line byextending its open end in the water tank upward.

With the described apparatus there is no di'iculty in maintaining 50%humidity in a house. The controls 5 and 6 need never 'be touched exceptin spring and fall Whenoutside moisture is high and the heater only runsoccasionally. At such times steam is shut off from the house. Steam doesnot appear in a visible cloud around the radiator a, nor does it loosenadjacent wall paper as might be supposed. There is no trouble from theradiator rusting in spite of tests showing that the system may introduceas muchA as ten gallons of Water to the house atmosphere in one day. The-benets from sucha System are tank and a float valve and coordinatedfeed pipe of relatively restricted capacity and directly connected tothe boiler and supplying a modicum of Water to the boiler and causing itto operate as a flash lboiler in a noiseless manner, a steam outlet pipeleading directly from the boiler to and discharging into the housespace, a condenser tank, a bleeder pipe from the steam pipe to thecondenser, regulating valves connected with the last mentioned pipes foradjusting the steam output from the boiler to the moisture requirementsof the house and for directing steam in excess n ci those requirementsto the condenser tank, and

drain connections for the condenser tank.

many and are varied; such as comfort at 70, less washing of windowcurtains due to keeping' down fine dust; furniture remains tight by notdrying out unduly; house plants thrive, and above all common colds andnose `and throat ailments are reduced. Y' 1 y It-Will be obvious-tothose skilled in the art to which the invention-relates that-modications may be made in details of construction and arrangement-Without departing fromthe spirit of the invention Iwhich is not limitedin respect to vsuch matters or to matters of mere form.
